“…Our experiments also tested word stimuli that systematically varied in both their word frequency and phonological neighborhood density characteristics, consistent with some previous convergence studies (e.g., Goldinger, 1998;Goldinger & Azuma, 2004;Pardo, Jordan, Mallari, Scanlon, & Lewandowski, 2013). Perceivers have previously been found to converge more to the spoken utterances of words with lower frequencies of occurrence within the English lexicon (Goldinger, 1998;Goldinger & Azuma, 2004).…”

“…Pardo and colleagues (2013) have recently investigated the influence of neighborhood density, in conjunction with word frequency, on phonetic convergence to shadowed auditory speech. Pardo et al (2013) proposed that should the lexical characteristics of word frequency and neighborhood density influence phonetic convergence, it would reflect the perceptual effort required to resolve the phonetic details available in the speech signal. This effort is reflected by the effects of word frequency and phonological neighborhood density on spoken word intelligibility: The most difficult words to identify are those with low frequencies and high phonological neighborhood densities (e.g., Bradlow & Pisoni, 1999;Luce & Pisoni, 1998).…”

Pardo et al also proposed that because talkers tend to hyperarticulate the vowels of words that are harder to identify-which has been found to be particularly true for words with high neighborhood densities (e.g., Munson & Solomon, 2004;Scarborough, 2013)-the greater distinctiveness of the articulatory information could itself lead to greater phonetic convergence.…”

Visibility of speech articulation enhances auditory phonetic convergence

Talkers automatically imitate aspects of perceived speech, a phenomenon known as phonetic convergence. Talkers have previously been found to converge to auditory and visual speech information. Furthermore, talkers converge more to the speech of a conversational partner who is seen and heard, relative to one who is just heard (Dias & Rosenblum Perception, 40, 1457-1466, 2011. A question raised by this finding is what visual information facilitates the enhancement effect. In the following experiments, we investigated the possible contributions of visible speech articulation to visual enhancement of phonetic convergence within the noninteractive context of a shadowing task. In Experiment 1, we examined the influence of the visibility of a talker on phonetic convergence when shadowing auditory speech either in the clear or in low-level auditory noise. The results suggest that visual speech can compensate for convergence that is reduced by auditory noise masking. Experiment 2 further established the visibility of articulatory mouth movements as being important to the visual enhancement of phonetic convergence. Furthermore, the word frequency and phonological neighborhood density characteristics of the words shadowed were found to significantly predict phonetic convergence in both experiments. Consistent with previous findings (e.g., Goldinger Psychological Review, 105, 251-279, 1998), phonetic convergence was greater when shadowing low-frequency words. Convergence was also found to be greater for low-density words, contrasting with previous predictions of the effect of phonological neighborhood density on auditory phonetic convergence (e.g., Pardo, Jordan, Mallari, Scanlon, & Lewandowski Journal of Memory and Language, 69, 183-195, 2013). Implications of the results for a gestural account of phonetic convergence are discussed.
